I’ve spent all the day trying to setup and install on my PC based on a Asus P9X79 DELUXE motherboard (that I was using with no problems with 2 gtx 590) 2 new Nvidia K20. I’m using Windows 7 64 bits.
My idea was to use one gtx590 for graphic purposes and then the 2 K20 for CUDA codes. I didn’t manage to make the configuration work, because of Driver problems.
It seems that when I install the K20C drivers the 590 driver are overwrite and the system doesn’t work.
I’ve also tried to remove the gtx590 and put another old card I had (geforce 8400) but the same problems happens. If I remove the 8400 driver and use a Standard VGA driver, then the PC is able to find the 2 K20C’s but if I try to run one of the CUDA samples or my actual compiled cuda codes, it crashes.
Has anyone actually done this successfully or has anyone failed (and why)?
